- the parameters for the fractions to be produced were entered into the higher-level measuring and control device. Since a particular desired particle size distribution in the different fractions is in each case given by the respective further use of the fracture to be produced, the fractions are usually stored as recipes in the higher-level measuring and control device and are selected accordingly. In the present example, the device was used for the production of 6 different fractions (BG 0, 1, 2, 3, 4 and 5).
- the recipes contain all the parameters of the optoelectronic and mechanical sorting systems and the conveyor technology.
- the fines (BG 0 and 1) of the Polybruchs was separated on a mechanical sieve with a mesh size of about 10 mm and then the separated portion with another me- 4 mm mesh size into BG 0 and 1 separated.

Frequency, also stored in the recipe, fed to the optical sorting system and separated over two tree levels, or three optical stages as follows: In the first stage BG 3 & 2 was separated from BG 4 & 5. As a separation limit, the recipe has a maximum length of 55 mm. BG 3 & 2 was separated into BG 3 and 2 in a second stage or a separation limit of 27 mm stored in the recipe. The BG 4 & 5 in a third stage and a separation limit of 100 mm in the BG 4 and 5.
- the software parameters were slightly varied with respect to separation limits of the individual fractions.
- the values with respect to the maximum or minimum permissible length of the fragments in the individual fractions were changed by a few millimeters (see FIG. 3).
- the separation limit for blowing between BG 2 and 3 was changed from 27 mm to 31 mm and between BG 3 and 4 from 55 mm to 57 mm.
- This program parameter change of only a few millimeters is already evident in the product properties (eg long-distance distribution), ie. H.
- the separation boundaries between the individual fractions can be flexibly adapted to the respective specification with high accuracy by simple recipe selection, or used in the context of the online control to achieve desired target values.
